7 Claims.

This invention relates toan improved furring means for use in producing plaster and other interior finishing walls in connection with adjacent building walls composed of masonry blocks, brick, concrete blocks and similar wall-forming units of denite form and dimensions. Particularly, the invention is useful in the application of metallic lathing in adjoining order with building walls composed of concrete block arranged in superposed horizontal courses.

At present, it is a difficult, time-consuming and relatively costly operation to apply a plaster-receiving base to a wall composed of concrete block. Considerable quantities of such block are used, particularly in forming the basement or foundation walls of residences and other buildings. It is often desirable to improve the appearance of cellar or basement walls composed of such block. The general practice at present, in accomplishing this end, is for a carpenter to nail or otherwise secure furring strips of wood to the concrete block after the latter has been laid in wall-forming order and to then apply a plaster-receiving lathing to the furring strips.

It is, therefore, an object oi' the present invention to simplify :and render less costly the operation of furring a wall composed of concrete blocks, or other similar units of masonry, by the provision of novel metallic furring brackets, the latter being of such construction that as the masonry blocks are laid in wall-forming order, the brackets forming the present invention will be received and positioned between the adjacent longitudinal ends of a pair of such blocks or masonry units, with the body portion of the bracketsV projecting beyond the inner surfaces or walls of said lblocks or units to function as a base for the quick attachment thereto of metallic lathing, composition panels or other interior wallnishing materials, the lateral projecting bodies of the brackets serving to space the finish wall structure from the masonry wall.

For a further understanding of the invention, reference is to be had to the following description and the accompanying drawing, wherein:

Fig. 1 is a perspective View of a iurring bracket formed in accordance with the present invention;

Fig. 2 is a horizontal sectional View taken through a wall composed of concrete block, and disclosing the use of the furring brackets in securing an interior finish wall structure to the outer wall;

Fig. 3 is a similar view disclosing the bracket when used in connection with a masonry wall composed of conventional brick;

Figrl is a detail perspective view disclosing a modified form of bracket, wherein vthe body of the bracket is formed with integral prongs for use in fastening lathing thereto;

Fig. 5 is a fragmentary perspective view of a further modied form of bracket, showing the construction of the same when adapted to the fastening of walls composed of prefabricated composition panels.

Referring more particularly to the drawing, the -bracket I comprising the present invention is preferably formed from a blank of sheet metal, which is bent or shaped by dies to provide a substantially rectangular body 2 composed of a Vertically extending front wall 3, parallel side walls l-l arranged at right angles to the front wall and inwardly directed rear walls 5 5, the latter extendingl in parallel relation to the front wall. The rear Walls 5 terminate at their inner ends in angularly bent wings 6 6, which are parallel with the side walls li and the inner ends of the wings 6 terminate in outwardly directed iianges 'I-l, which lie in planes parallel to those of the walls 3 and 5.

In the use of these brackets, the same are inserted between the longitudinal ends of contiguous pairs of masonry Wall-forming units, particularly concrete blocks of the standardized type indicated at 8. These blocks are formed at their ends with recesses 9, and the flanges 'I engage a wall at the time the latter is being erected. Itv

has been found desirable to maintain the wings 6 in slightly spaced relationship, and this may be positively accomplished by providing one vof the wings 6 of each bracket with one or more teats I0, the latter serving to hold the wings separate even though crowded by adjoining blocks.

After the wall has been erected with the brackets I in associated relationship therewith, metallic lathing II which may be of the so-called expanded metal type is secured to the projecting bodies 2 of said brackets. This may be accomplished in many different ways, but in a preferred embodiment of the invention, the walls 3 and 4 are formed with the slotted openings, indicated at I 2. The lathing is placed against the front walls 3 of said brackets and tying Wires I3 are passed. through the lathing and also through the openings I2, the ends of the wires being twisted or knotted to hold the lathing in secured engagement with said brackets. A plaster composition I4 may then be applied to the metal lathing for the purpose of completing the inner finish wall, which may be papered, painted or otherwise decoratively completed.

Due to the projecting body portion of each bracket, it will `be noted that there is a space l5 formed between the outer wall composed of the blocks 8 and the inner iinish wall. This space is desirable for precluding the transmission of moisture to the inner wall through the more or less moisture pervious outer wall and, also, to provide a space for the reception of electrical conduits, switch boxes, outlets and the like- In addition, by spacing' the wings 6, the space I5v will be in communication with the spaces produced by the recesses 9 in the blocks 8, providing improved air circulation and the elimination of moisture in the inner wall structure.

As shown in Fig. 3', thebracket is shaped for adaptation to building walls composed of conventional brick. This form of the invention is essentially the same as thatV previously described,

with the exception that the wings` 6-6 of each i have been forced through the wire lathing, the

same are suitably bent and ilattened to lie parallel with the rontwall 3..

In Fig. 5, the body of each bracket is formed with an outwardly directed web IT, wherein the outer edge of the web terminates in reversely directed prongs !8. In this form of the invention, composition walls, composed of prefabricatedpanels, may be conveniently attachedto the brackets by the insertion of the prongs I8 into the opposite edge portions of thepanels, where the prongs are concealed and a: close union obtained between the adjoining edges of the panels.

In view of the foregoing, it will be seen that the present invention provides a simple, radially applied and inexpensive bracket adaptedy primarily for use as a furring for the convenient erection of inner walls in connection with outer masonry walls composed of standardized units. The brackets are inserted a-t the time thel outer wall is being laid and by the inclusion of the prising a sheet metal member formed from a single blank of material` and bent. to. provide-a substantially rectangular bod'y portion consisting of front, side and back walls, wings integrally formed with said back walls and disposed for engagement with the adjoining ends of a pair of contiguous wall-forming. blocks, outturned flanges integrally' formed with the' distal ends of said wings and cooperative with said wall blocks to retain the bracket against movement in connection therewith, and means formed with the body portion of said bracket for attaching thereto an inner finish wall so that the body portion of said bracket will space the outer masonry Wall from the inner finish wall.

2. A furring bracket comprising an integral sheet metal member formed to provide a substantially rectangular body portion composed of a front wall, parallel side walls, a pair of rear walls arranged in parallel relation to the iront wall, a pair of wings extending rearwardly from the inner edge portions of the rear walls and laterally directed flanges at the rear edges of said wings, the spaces formed between said rear walls and said flanges possessing a depth to accommodate the ends of a pair of contiguous wallforming blocks, and registering slots provided in the front and side walls of the body portion of said bracket for the reception of wall tying devices.

3. The combination with a masonry building wall composed of a plurality of preformed blocks rranged in horizontal. and superposed courses, of a plurality of furring brackets mounted in said wall between the adjoining ends of contiguous blocks, each of said brackets comprising a sheet metal member bent to provide a substantially rectangular body portion and a pair of inwardly directed wings, the: latter having their inner ends terminated in laterally directed flanges, the recesses formed between said body portion, said wings and franges being of such depth. as to receive therein the adjacent ends ets adapted to be mounted in said wall. at the time' oi' its erection, each of said brackets comprising a substantially rectangular body portion composed of a front wall', side walls and apair of rear walls,- the inner ends of said rear walls terminating in a pair of spaced wings, laterally directed' flanges formed with the distal ends 0f said wings, said wings being adapted for engagement with the adjacent ends of a pair of adjoining wall block with the front surfaces of said blocks in contact with the rear walls of said body portion and with said flanges disposed in the recesses of' said blocks, and an inner wall structure' secured to the body portions of said brackets and spaced thereby from said masonry wall.

5. A building wall' comprising a plurality of pre-formed cernentitious blocks arranged. in horizontal superposed courses, the adjoining endsA of said blocks having registering flanges, furring bracket means supportedr by said wall, said brackets having flat front walls, rearwardly directed side walls and back walls, wing extensions connect'ed with said back Walls and projecting between the flanged ends of adjoining blocks, outturned' ilanges on said wing extensions engaging the rear surfaces of said block flanges, and plaster-receiving lathing secured to the flat front walls of said brackets to be supported by the latter in spaced relation from said block wall.
